Cyber hygiene of the digital twin of the civil aviation occupational safety management system in the context of quantum transformation

The subject matter of this article is cyber hygiene of the digital twin of the occupational safety management system of engineering and technical personnel of civil aviation. The goal is to develop a methodology for assessing the cyber hygiene of the digital twin of the occupational safety management system of engineering and technical personnel of civil aviation in the context of transformation into the quantum future. The tasks: to develop a methodology for assessing the state of the digital twin of the occupational safety management system of engineering and technical personnel of civil aviation using an integral cyber hygiene index; to develop a model of transitions of the functional state of the digital twin, allowing to predict its cybersecurity, cyber vulnerability and recovery capabilities in case of cyber-attacks; to determine cyber hygiene measures for the digital twin in the context of quantum transformation. Results: a methodology for assessing the cyber hygiene of the digital twin of the occupational safety management system of engineering and technical personnel of civil aviation in the context of quantum transformation has been developed; it has been proven that the process of transition of the cyber hygiene system from one state to another, in response to the measures taken, is an iterative process, which allows dynamically monitoring the effectiveness of the taken measures on DT cyber hygiene and predicting its further state; algorithm for the sequence of stages of assessing the state of DT cyber hygiene and their relationship within a cyclic process has been developed. Conclusions: a method for assessing the state of DT cyber hygiene has been developed, which, due to its iterative nature and the use of Markov chains, allows determining the probability of the transition of the cyber hygiene system from one state to another, as a response to the measures taken. The application of this method in practice will allow dynamic monitoring of the cyber hygiene of the digital twin and the effectiveness of the measures taken, as well as predicting its future state.
